2 12 Miscellaneous Accessories At Industrial Scientific, we know that no two working environments are the same. Loud or quiet. Hot or cold. Indoors or outdoors. Confined space or open field. No matter what the working environment, it s absolutely essential that our customers have the tools to best adapt to their specific situations. Industrial Scientific accessories are designed to meet the individual needs of each user, and enable them to operate with confidence. Industrial Scientific s external alarms provide additional protection in high-noise work environments. External Alarms: (a) Audible/Visual Latching External Alarm (103 db) (b) Audible/Visual External Alarm (90 db) a b c Many instrument models from Industrial Scientific offer datalogging as an option. The datalogging feature expands the functionality of the instrument with the ability to store or log the recorded gas readings. The stored data can then be used to calculate exposures during a work shift, record peak gas readings, or simply identify instrument usage patterns. Datalogging Kits include appropriate software, connecting cables and information for using the datalogging functions and retrieving stored data.

The 4800 Controller from Industrial Scientific is an 8-48 analog input controller. With its optional onboard relays, the 4800 can control alarms, fans, horns, etc., when alarm conditions are reached. Being fully programmable, relays can be set to activate from multiple channels, or multiple relays can be programmed to a single channel. Time delays can also be programmed for each relay. This allows the relays to activate after alarm conditions are met for specified periods, or de-activate after a specified time prior to an alarm. Along with monitoring analog signals, the 4800 Controller can also monitor up to 72 digital ModBus RTU inputs. The 4800 can be set up as a ModBus RTU master unit to monitor these channels, or it can be set up as a ModBus RTU slave device. As a ModBus RTU slave device, the 4800 Controller can communicate to SCADA, HMI, and PLC controlled systems. With a telephone line interface, the 4800 Controller has remote call-out capabilities. This allows the controller to phone, fax or page alarm notifications to users. Phone lists are user programmable and can be entered in a priority. The 4800 can also be remotely programmed via the telephone. To keep track of events, the 4800 Controller has a built in event log. The event log will store 1,000 events. Events consist of calibrations, peaks and alarms. The event log can be viewed via a local printer connected to the 4800 Controller, or through a PC.

A common unit of measurement is a percent of the LEL. ma: Milliamp A unit of electric current expressed in amperes. 4-20 ma signals are commonly used analog signals in industrial electronics, where 4 represents the lowest value, for instance 0 ppm, and 20 represents the maximum, for instance, 999 ppm. PEL: Permissible Exposure Limit Level of gas (in ppm) a worker can be exposed to 8 hours a day/ 40 hours a week for the rest of their life with no long term health effects. PID: PhotoIonization Detector An instrument that utilizes ultra-violet light energy to ionize and detect the presence of an unknown gas or vapor. ppm: Part Per Million A common unit of measurement for toxic gases. This term literally means one part out of one million possible parts. TLV-STEL: Short Term Exposure Limit The average amount of gas (in ppm) a worker can be exposed to in a 15 minute period with no long term health effects. This may occur 4 times a shift with one hour between 15 minute exposures. TLV-TWA: Time Weighted Average The average amount of gas (in ppm) a worker can be exposed to over a certain time period. This time is defined as 8 hours to represent a normal work day. TLV: Threshold Limit Value A term used to signify limits in gas exposure. TLV is used as a prefix for TWA and STEL. UEL/UFL: Upper Explosive Limit/Upper Flammable Limit The maximum concentration at which a gas will explode. VAC: Volts Alternating Current An electric current that reverses direction at regular intervals. VDC: Volts Direct Current An electric current of constant direction. VOC: Volatile Organic Compound Any compound containing carbon, except methane, that can be readily vaporized.

Intrinsic safety is a design technique applied to electrical equipment and wiring for hazardous locations. The technique is based on limiting energy, electrical and thermal, to a level below that required to ignite a specific hazardous atmospheric mixture. How is intrinsic safety defined? Intrinsically safe equipment and wiring shall not be capable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition of a flammable or combustible atmospheric mixture in its most easily ignitable concentration. Who verifies intrinsic safety? Equipment is tested and certified for intrinsic safety by independent third party agencies, such as Underwriters Laboratories (UL), Canadian Standards Association (CSA), Factory Mutual Research Corporation (FM) and the Mine Safety and Health Administration (MSHA). Independent testing ensures that your gas monitoring equipment is not only designed to be intrinsically safe, but meets all required standards for intrinsic safety. FUEL FIRE TRIANGLE SOURCE OF IGNITION OXYGEN Ref: R. Stahl Intrinsic Safety Primer 1988 National Electrical Code Article 504-2 Definition of a Intrinsically Safe Circuit 1996 A circuit in which any spark or thermal effect is incapable of causing ignition of a flammable or combustible material in air under prescribed test conditions.
